My flexibility never decreased, so I don´t see the need to stretch in general.I do however need more flexibility in the hips and shoulders for ultra-wide sumo squatting and Olympic lifting, so I´ll incorporate some mobility work for the hips (which doesn´t stretch the muscles and can be done before training without decreasing your strength for the day) and maybe a stretch or two after shoulder/pec work.

I do triceps, shoulder, pec, lat, and wrist stretches pretty much daily because I have a lot of upper body tightness and a history of getting tendinitis in my wrists. Other than that, I stretch my hamstrings and ankles sometimes.

I didn't but I started to get less flexible. It never really got in the way of lifting but I have odd dyspraxic walking issues some days and as my hamstrings got tighter I started to get more days were it took longer for it to not be stuff/sore feeling. I'll sometimes stretch after a work out but mostly I do on off days.
